Tax maps are the single most important tool in the real property assessment process. It is not possible to establish an adequate real property tax record and accounting system without tax maps, for they are the basic foundation of the system. They establish a permanent link between the real properties in the field and the property assessment and tax records in the office. They are indispensable in the discovery of property and the identification of property ownership. They simplify the task of property description and tie together all property records, including field appraisal and assessment sheets and assessment tax rolls. They also provide the public with vital real property information. Finally, tax maps make possible the establishment of a property record system that is easily adapted to data computerization. The objectives of the Tax Mapping operations is to establish a complete inventory of all real properties, to provide a permanent link between real properties and office records, to identify the ownership of every piece of real property and to account for the total land area of province, cities or municipalities.

They completed very satisfactorily the Tax Mapping Project for seven (7) Barangay’s namely, Kat-Bayani, Kay Buto, Mag-Ampon, Pinagkamaligan, San Isidro, Tabing-Ilog and Wawa in four (4) years. However, said Tax Mapping program was effectively suspended in the year 2010 to give way for the General Revision of Assessment (GRA). Year 2011, our Municipality attained the highest increase in taxable assessed valuation in real property of three hundred ten percent (310%), over the highest increase in the entire province of Rizal due to Tax Mapping operations and General Revision of Assessments (GRA). It may be the dream to reach to the zenith of all our tax mapping operation, of the Municipal Assessor’s office but we cannot do it without the fullest support of the local government units particularly, the Honorable Mayor RAFAEL A.

For the past five months thru the joint effort of all the personnel of this office we are proud to announced that we have almost 65% completed the activities of Tax Mapping operations for twelve barangays (12).
